Carbon Steel Solutions from Solitaire Modern Metals
Carbon steel products are a versatile alloy composed of iron and carbon, widely recognized for their strength and durability. But what exactly is carbon steel? It is classified into grades based on carbon content, such as high carbon steel and low carbon steel. High carbon steel, containing 0.6%-1.0% carbon, is exceptionally hard and strong, making it suitable for cutting tools. In contrast, low carbon steel, with up to 0.3% carbon, is more malleable and weldable, making it ideal for applications like automotive panels.
Referring to a carbon steel grades chart can help in choosing the appropriate type based on its chemical composition and properties. Elements such as manganese and silicon influence its hardness, ductility, and wear resistance. These characteristics make carbon steel indispensable in construction, manufacturing, and engineering. Its diverse properties and grades allow it to effectively meet a wide range of industrial demands.
